OIL-BURNER.

To all whom it may concern:

Be it known that I, HARRY M. DAGGETT, a citizen of the United States, residing at 1-109 East Eleventh street, Oakland, in the county of Alameda and State of California, have invented a new and useful Oil-Burner, of which the following is a specification in such full and clear terms as will enable those skilled in the art to construct and use the same.

This invention relates to a burner for oil and its object is to produce a very simple and eflicient burner which will not carbonize and which can be used in an ordinary household stove with good results. The burner is so constructed that it can be easily cleaned should it become necessary.

Another object of the invention is to produce a set of castings which will not burn out easily, the flame being so placed with respect to the parts of the burner as to avoid heating it unduly.

In the drawing, in which the same numeral of reference is applied to the same portion throughout the several views, Figure 1 is a perspective view of a stove having the burner applied thereto, a portion of the stove being broken away to show the position of the burner, and Fig. 2 is a central vertical sectional view of the burner.

The numeral 1 represents the stove which may be of any desired shape or size, the stove having a common form of draft door 2. The ordinary coal grate bars are removed and in their place the plate 3 is inserted, said plate having a hole in the center thereof and having two flanges 4: and 5 around said hole. The inner flange 4 acts to confine the air passing to the burner to prevent the oil from burning too far down whereby the burner would be heated too much. The collar 5 afl'ords means whereby the half annular rings 6 and 7 are supported, said half annular rings preventing the intense combustion from taking place too close to the oil supply pipe, whereby the oil would be carbonized in said supply pipe.

The action of the burner is something like the action of the common form of Bunsen burner in that the oil is prevented from having a supply of air large enough to burn it completely until it passes above the top of the plates 6 and 7. For the reason just set forth the large plate 3 is never heated hot enough to be injured, and only after long Specification of Letters Patent.

usage is it necessary to renew the plates 6 and 7 The plate 3 supports a drip pan 8 by means of two rods 9. The supply pipe 10 is connected with the bottom of the drip pan, a cut ofl Valve 10 being provided for the regulation of the supply, the oil passing up through a pipe 11 in the top of the drip pan to the burner head 12 on the upper end of the short pipe 11.

In order that particles of carbonized fuel may not drop down into the oil pipe 2- cap 15 is loosely placed thereon, said cap causing an even distribution of the oil as it escapes from the top of the burner head 12.

The burner head has a large flange 16 at its base, the object of said flange being to prevent the oil which may happen to flow over the edge of the head without being vaporized from dropping straight down into the drip pan, since when it strikes the flange it will be detained long enough to be completely heated and vaporized, the incoming air carrying it to the flame.

The burner can be cleaned by simply lifting off the cap 15.

In order that there may be a flame burning for a short time after the oil supply has been stopped a ring of asbestos 18 is secured in a groove in the top of the flange at the bottom of the burner head. This causes the burner to cool off slowly and avoids danger of a possible explosion of a small amount of oil after the flame has disappeared.

Having thus described my invention what I claim as new and desire to secure by Letters Patent of the United States is as follows:

1. In an oil burner, a plate having an opening therein, a pair of annular flanges surrounding said opening, an oil supply pipe passing through said opening and having a burner head, a loose cap carried by said burner head, half annular rings forming means to confine the air passing through the opening in the plate, and means to regulate the supply of fuel to the burner, substantially as described.

2. In an oil burner, a plate having a hole therein, a pair of annular flanges surrounding said hole and integral with said plate, a drip pan carried by the plate, an oil supply pipe passing through the drip pan, a

flanged burner head carried by the top of 110 the oil pipe, a loose cap on the burner head, and means to regulate the supply of oil to the burner, substantially as described.

3. In an oil burner, a plate having an opening therein and having two annular flanges surrounding said opening, two half annular rings carried by one of said flanges, a drip pan supported by the flanged plate, a pipe extending from the drip pan through the flanged plate, a burner head having a flange at its base on the upper end of the pipe from the drip pan, a loose cap carried by the burner head, and means to regulate the supply of fuel to the burner, substantially as described.

In testimony whereof I have hereunto set my hand this 21st day of June A. D. 1909, in the presence of the two subscribed witnesses.
